WILLIAM EDWARD TURNER, OF ESOANABA, MICHIGAN.

SLE IGH-RUN N ER.

Application filed August 22, 1908.

To all whom it may concern:

Be it known that I, WILLIAM E. TURNER, a citizen of the United States,and a resident of Escanaba, in the county of Delta and State ofMichigan, have invented a new and Improved Sleigh-Runner, of which thefollowing is a full, clear, and exact description.

This invention is an improvement in sleigh runners, having in view aconstruction in which the runners are in the nature of I-beams, eachhaving a knee applied thereto provided with opposed jaws, with the benchor beam of the sleigh provided with approximately semi-circular groovesnear each end and at both sides, receiving the jaws of the respectiveknees, which admit of a slight relative endwise movement of the runnersand thus relieve the connections of the bench of undue shock.

Reference is to he had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side view of a runner embodying my invention, partly incentral vertical section; Fig. 2 is a plan of the runners and theconnecting bench or cross-beam, and Fig. 3 is a cross-section throughone of the runners substantially on the line 3-3 of Fig. 2.

The runners proper as preferably constructed are in the form of I-beams5, each comprising a bottom flange, a top flange, and an intermediateweb connecting the flanges together, this form of runner enabling theirconstruction of standard rolled metal without additional shaping otherthan curving the forward ends. Intermediate the length of each runner issecured by rivets, bolts or such other devices, a knee 7 which is provided with jaws 8 having opposed curved edges, as clearly illustrated inFig. 2. Over the knee of each runner is placed a strap 9 which isriveted or otherwise attached at its Specification of Letters Patent.

opposite ends to the runner, and is further secured directly to the jaws8, for which puri Patented March 9, 1909.

pose the latter are provided with studs or projections 10 on their topfaces entering and snugly fitting corresponding openings in the strap.

The runners are connected together by the conventional cross-beam orbench 11, which, in the present instance is provided with. metal-linedgrooves near each end and at opposite sides, which receive the roundedends of the jaws and conform thereto. This particular constructionadmits of relative endwise movement between the runners and relieves theconnecting ends of the crossbeam 11 of undue strain or shock when therunners strike an obstruction.

The making of the runners of standard rolled metal permits of theirmanufacture at a relatively low cost, and of light and strongconstruction, and the particular cross-sectional form of metal adoptedis especially applicable to the attachment of the knees 7 not only fromthe fact that the top flange of each runner affords a substantialseating surface for the knee but also for the reason that the bolts orrivets may be passed through this flange, as shown, in securing the kneein place.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

The combination of sleigh runners, a knee carried by each runner havinga pair of opposed jaws, each jaw having a lug on its upper face, a benchhaving its opposite end portions engaged between the pairs of jaws, anda strap having openings snugly fitting the lugs of the jaws and havingits ends attached to the runner.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
